If A, B, C are three non- collinear points with position vectors respectively, then show that the length of the perpendicular from C on AB is
Draw a rough sketch of the curve and find the area of the region bounded by curve y2 = 8x and the line x =2.
Sketch the graph of y = |x + 4|. Using integration, find the area of the region bounded by the curve y = |x + 4| and x = – 6 and x = 0.
Find the image of a point having position vector: in the plane .
Let B be root of point A in the plane can of AB : is
Substituting these values of x, y and z in the plane 3x - y + 4z = 2,
Thus, by mid-point formula,
